Adipose tissue inflammation in diabetes and heart failure

Adipose tissue inflammation induces systemic insulin resistance in persons with obesity and heart failure, and has a crucial role in the progression of these diseases. Chronic inflammatory processes share a common mechanism in which increased production of reactive oxygen species activates p53 and NF-kappa B signaling, leading to up-regulation of pro-inflammatory cytokine expression and impairment of glucose metabolism. Since inhibition of these processes could slow the progression of various diseases, targeting adipose inflammation has the potential to become a new therapeutic approach for diabetes and heart failure.
